KNIFE FOR MINERS.

:JPBCIFICATION forming part of Letters Patent No. 313.41%, dated March8, 1885.

To all 211710727, it may concern:

Be it known that I, GEORGE FREUND, of Durango, in the county of La Plataand State of-Oolorado, have invented a new and Improved Miners Knife, ofwhich the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved knife forniiners use for facilitating the cutting and capping of fuses, openingcans, and for other similar purposes.

This invention',which is an improveinenton the miners knifefor whichLetters Patent No. 297,375 were issued to me on the 22d day of April,1884., consists inthe combination, with a knife-casing. of a can'opener,a cork-screw held in the blade for splitting or cutting the fuse, and in"arious details and parts of construction and combinations of the same,as will be fully described and set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a longitudinal elevation of my improved knife, showing allthe blades closed. Fig. 2 isasimilar view showingthecan-opener bladeopened. Fig. 3 is a view of the opposite side, showing the main bladeand the fuse cutter or splitter open. Fig. 4 is a like view showing allthe blades closed. Fig. 5 is a longitudinalelevation of the fuse-cutterblade, showing the same provided with aeork-screw.

A blade, A, is pivoted in a casing, 13, and is provided with a notch, O,the bottom of The easing B is provided with a corresponding notch,

' D, the bottom of which is also designed to be screw-threaded. The endof a fuse is placed in the notch D, the blade A is pressed down ward,and thereby a screw-thread is formed on the end of the fuse, thusadapting the fuse to be screwed into the cap. If desired, the fuse canbe passed into the cap, and the fuse and cap placed in the notch D, andthe blade A pressed down to form the screw-thread in the cap and fuse,and thus prevent the cap from slipping oii' the fuse. One end of thecasing is provided with a notch, E, for receiving the end of the fuse tobe split longitudinally. A blade, F, pivoted inthe casing, has aprojection beyond the pivot, which projection forms the blade G forsplitting the fuse.

The blade F is adapted to be folded in a recess, H, in the side ofv thecasing, in the bottom of which recess a how-shaped spring, J, isheld,whichis provided withaprojection, K, held in a notch in the side ofthe casing, thus leaving both ends of the spring J free. The end J ofthe spring is provided with a slight recess or groove for receiving theedge of the blade F, and theopposite end is providedwith a head, J,provided with transverse grooves and with a longitudinal groove forreceiving the point of the blade F. When the blade F is folded in therecess H, it presses back the head J and passes under the same. If theblade F is to be opened, the thumb-nail is placed in one of the smalltransverse grooves in the head J and the said head pressed against ortoward the end of the recess H, whereby the said head is moved from theend of the blade F, which is thus released, permitting the opposite end,J, of the spring J to throw the said blade outward. thus acts as a lockto keep the bladein place, and as a spring for throwing it out when released. Notches are formed in the blade F and in the case forcuttingthreads on smaller fuses. If desired, the blade F may consist/ofa corkscrew, I, over which a casing, L, isscrewed, forming the blade. Ifthe corkscrew is to be used, the casing L must be removed. The casing Lor the blade F can be used as a spoon for digging out giant-powdercandles to insert the fuse with cap.

In that end of the casing B opposite the one in which the blade A ispivoted, and at the same end as that in which the blade F is pivoted, acan-opener, M. is pivotedgvhich is pro vided. with a point, a sharpedge, and with a curved roughened part, N, to prevent the blade fromslipping on the can. The part 0 of the end of the casing is alsoroughened, notched, or serrated to prevent the handle from slipping onthe can. The can-opener blade M is pivoted by a pivot, P, passingthrough a slot, O, in one end of the blade M, which is also providedwith an L-shaped or like slot, R, extending to the edge, through whichslot a pivot or screw, S, passes. In

one side of the blade M a notch, T, is formed, which is adapted toreceivea pin, U, formed on the end of a springflV, secured on theeasing. WVhen the can-opener blade M is folded The spring I TOO withinthe casing. the pin U snaps into the notlt h T in the blade. .thuslocking, the blade in place. Alter the blade M has been swung out toopen it, it is pressed toward the end oftlie casing to cause thepin S tobe at the upper end of the slot R for the purpose of holding thecan-opener in position. ll'the can-opener blade is to he closed. it isfirst pulled in the direction from the end of the casing to release it,and is then folded in the casing, in which it is locked by the spring W.The can-opener blade is provided with a groove, 0, for receivin; thethumb or finger nuil for opening it.

Having thus dest-rihed my invention, what I cluin as new, and desire tosecure by Letters Patent, is

1. ln a knife, the combination, with the case B. oftlte blndc llLimvingthe slots Q and R. and of the pins P and S in the knife ease.substantially as herein shown and described. I

2. in n knile, the combination, with the case B, having its end portion,0, serrated or roughened, of the can-opener blade M, having part of itsback edge roughened, substantially as herein shown and described.

3. iii a knife, the combination. with a handle-case having a recess inoneside, of ablade adapted to be folded within the said recess, and ot'a spring secured in the bottom of the recess and having both ends free,one end being, provided with a head having a longitudinal groove toreceive the point of the blade, substantially as herein shown anddescribed.

4. In a knife, the combination, with the case B, having a recess, H, ofthe spring J, having both ends tree, and provided with a projection,

K, for holding it in place, and the blade F,

pivoted in the case, substantially as herein shown and described.
